Removes up to 95% of all mineral salts and heavy metals from tap water. The life of the membrane will depend on the quality of the filtered water and the quantity and quality of the water needed.

This is the highest production membrane currently available in this size and configuration, without using much higher cost membranes that require much higher inlet pressures, pumps and motors.\u003c\/p\u003e\n\u003cp\u003eThe 150 GPD specification is based on the following parameters:\u003c\/p\u003e\n\u003cp\u003e1 - Water Temperature: 25ºC\u003cbr\u003e2 - Water Pressure: 60 psi (4.3 kg\/cm3\u003cbr\u003e3 - TDS (Total Dissolved Solids): 500 ppm (0.7 EC)\u003c\/p\u003e\n\u003cp\u003eTherefore the production will increase or decrease according to variations in the\u003cbr\u003eabove water conditions. Example:\u003c\/p\u003e\n\u003cp\u003eWater production will decrease by 3.6% for each degree below 25º C. So, if your\u003cbr\u003ewater temperature is 15ºC, then; 10º (less) x 3.6% = 36% decrease. Now, 20 L\/h can\u003cbr\u003ebe about 13 L\/h.\u003c\/p\u003e\n\u003cp\u003e1 - Or if the temperature is even lower, let's say 10ºC, then: 15º (less) x 3.6% = 54%\u003cbr\u003edecrease. 20 L\/h can now be as low as 9 L\/h.\u003cbr\u003e2 - Also, at the same time if the inlet pressure is lower than 60 psi (4,3 kg) then your\u003cbr\u003eproduction will also decrease.\u003cbr\u003e3 - Also if the TDS is higher than 500 ppm (EC higher than 0.7), then again, you will\u003cbr\u003ehave another lower production rate. The higher the EC, more inlet water pressure is\u003cbr\u003eneeded.\u003c\/p\u003e\n\u003cp\u003eGrowmax Water has designed its reverse osmosis systems for the Hydroponic and\u003cbr\u003eGardening markets. Because we are not using pressurized holding tanks, different\u003cbr\u003efrom residential RO units, they have designed their units to reject much less water\u003cbr\u003ethan with conventional units.\u003c\/p\u003e\n\u003cp\u003eMost RO systems are designed to reject 4:1, 5:1, 6:1 or more. This means for each\u003cbr\u003elitre of water produced, 4, 5 or 6 times of the amount of water is needed and is sent\u003cbr\u003eto the drain (or garden).\u003c\/p\u003e\n\u003cp\u003eGrowMax units are designed to reject ONLY 2:1. This saves a lot of water!\u003cbr\u003eHowever, the downside to this design is that if the TDS or EC is very high, more than\u003cbr\u003e500 ppm (0.7 EC) then the lifespan of the reverse osmosis membrane can be\u003cbr\u003ediminished.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eWhat's Included?\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 x GrowMax Reverse Osmosis Membrane - 150 GPD\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"GrowMax","offers":[{"title":"Default Title","offer_id":48041302950220,"sku":"GMWMEMB150","price":84.95,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0789\/3044\/4620\/files\/growmax-mega-grow-membrane-gpd150.jpg?v=1713788092","url":"https:\/\/hytachydroponics.com\/products\/growmax-reverse-osmosis-membrane-150-gpd","provider":"Hytec Horticulture","version":"1.0","type":"link"}
